Best Time to Visit

Oahu

The best time to visit Oahu is during the spring and fall months—April to June and September to November—when the weather is warm and comfortable, with fewer tourists and more affordable accommodations. Temperatures range from 24°C to 29°C (75°F to 85°F), making it perfect for outdoor activities like surfing, snorkeling, and hiking.

Winter (December to March) is also a popular time to visit, especially for those looking to escape colder climates. Temperatures remain mild, between 21°C and 27°C (70°F to 80°F), though winter is also the rainy season. However, it’s also the best time for surfers, as the North Shore experiences massive waves and world-class surf competitions during this period.

Summer (June to August) is the busiest and hottest time, with temperatures reaching up to 32°C (90°F). While summer is ideal for beach days and water sports, expect larger crowds, especially in popular areas like Waikiki.
